Which of the following is an acidic oxide?

Options

  1. ACO
  2. BNO
  3. CN ₂ O
  4. DN ₂ O ₅

Correct answer

D. N ₂ O ₅

Step-by-step solution

Oxide classification depends on the element's position in the periodic table and its oxidation state. Non-metal oxides are typically acidic while metal oxides are basic, though exceptions exist such as neutral oxides. Carbon monoxide ( CO ), nitric oxide ( NO ), and nitrous oxide ( N ₂ O ) are all neutral oxides that do not react with acids or bases. Dinitrogen pentoxide ( N ₂ O ₅ ) is acidic, reacting with water to form nitric acid: N ₂ O ₅ + H ₂ O 2 HNO ₃ . It also forms salts with bases. Thus, N ₂ O ₅ is the aci
